A Service Before Selling: Necessary or Money Wasted?
Uhrenkontor editorial team · · Updated · 7 min read

A service before selling a luxury watch rarely pays for itself. A manufacturer overhaul is expensive and takes weeks to months, but seldom raises the pre-owned price by the same amount, because dealers factor a due service into their offer anyway. The exception is a watch that does not run: a repair after a written estimate can make sense.
This guide answers one question: "Should I have the watch serviced before I sell it?" It covers only a service shortly before a sale, not general service intervals.
What does a service cost, and what does it return when you sell?
An overhaul at the manufacturer is expensive, depending on brand, calibre and complications, and takes weeks to months. A written estimate from the brand or a watchmaker tells you what it would cost for your watch. On the pre-owned market a fresh service does not as a rule raise the price by the same amount. Dealers factor in a service anyway if the last overhaul was some years ago, and many buyers prefer to have the watch serviced themselves after purchase.
Then there is the time: while the watch is at the workshop, you cannot sell it. And a service changes the watch, as the next sections show.
When does a service really affect the price?
- The watch does not run, or runs noticeably inaccurately: a working watch is easier to assess and to sell. A repair can make sense here, but only with a written estimate first. More on this in the guide Selling a broken luxury watch: repair it first or sell as it is?
- The service is recent and documented: that is an argument for buyers, but only if the record exists. Keep your service receipts. A record with date, workshop and the work carried out says more than any verbal statement.
Service before selling: what applies in which situation?
| Situation | Service before selling? | What to do instead |
|---|---|---|
| Watch runs, last service long ago or unknown | No | State the service history honestly |
| Recent service, record available | No further service needed | Include the record with the watch |
| Automatic watch has stopped after lying unused | No | Wind it and observe it for a few hours |
| Mechanical watch suddenly runs fast | No, demagnetising is often enough | Have a watchmaker check it |
| Quartz watch has stopped | No, a battery change is usually enough | Have the battery changed by a professional |
| Watch does not run or is damaged | Only after a written estimate | Show the estimate when you sell |
| Vintage watch, roughly pre-1990 | Not without a specialist's advice | Keep the original parts |
| Scratches on case or bracelet | No polishing | State the signs of wear and photograph them |
When does a service do harm?
On vintage watches, manufacturers frequently replace the dial, hands or luminous material with new parts during a service. For collectors that destroys the original condition and with it part of the value. For watches made before roughly 1990 the rule is: ask a specialist before the service whether the original parts will be kept.
The manufacturers say so openly. During a service Rolex replaces every component that no longer meets its functional and aesthetic specifications with a genuine Rolex part. Omega upgrades movements without a serial number to the latest movement version where applicable. On a modern watch that makes sense; a collector's piece loses its original condition.
Why should you not have the watch polished?
The same applies to polishing. A polished case loses its edges and its material, and that cannot be undone. Fine scratches are signs of wear, not faults. Leave the watch as it is.
A manufacturer service often includes polishing. Rolex refinishes the case and metal bracelet during a service, and at Omega polishing the case and bracelet is one of the steps of a complete service. If you have the watch serviced anyway, clarify in writing beforehand whether the case can be left unpolished.
What should you do instead?
- Wind the watch and check that it runs and that the functions (date, chronograph) work.
- Clean the case and bracelet with a soft cloth, and on water-resistant watches with lukewarm water and mild soap. If the crown screws down, screw it fully home first. No ultrasonic cleaners on leather straps or where water resistance is uncertain.
- Gather all records, links and accessories together. Which parts and papers count is explained in the guide Full set, box and papers, watch only.
- Describe honestly when the last service was, even if the answer is "never".
Why should you state the service history honestly?
The service history is part of the description of the watch. Under Article 197 of the Swiss Code of Obligations the seller is liable for warranted qualities; if you state "freshly serviced", you should be able to prove it. Under Article 199, an exclusion of warranty does not protect a seller who has fraudulently concealed a defect.
At Uhrenkontor, the watch is checked at the handover, and the offer is subject to its condition matching the description.
Conclusion
A service before selling rarely adds up. Sell the watch in well-kept, original condition and state the service history. At Uhrenkontor over 25 partner dealers assess the watch exactly as it is, and an overdue service is taken into account in the offer rather than being a reason to decline. You state the service history in the online form. The full picture is in the guide How to sell a watch in Switzerland.

Frequently asked questions
Does a watch have to be serviced before it is sold?
No. Dealers also buy watches with a service due and factor the overhaul into their offer. What matters is that you state the service history honestly, even if the last service was long ago or is unknown. The exception is a watch that does not run at all: then a written estimate helps you decide.
Should I have scratches polished out before selling?
No. Polishing removes material and changes the edges of the case, and that cannot be undone. Fine scratches are signs of wear, not faults, and collectors prefer an unpolished case. Dealers decide for themselves whether to refinish a watch and factor that into their offer.
Is a service worth it on a vintage watch before selling?
Usually not, and it can do harm. During a service the dial, hands or luminous material may be replaced with new parts, and for collectors the original condition is then lost. Have a watch made before roughly 1990 assessed by an experienced specialist before any work. If work is needed, ask whether replaced parts will be returned to you.
What do I state if I do not know when the last service was?
Write exactly that: "last service unknown". It is an honest statement, and dealers will then usually factor a service into their offer. Do not invent a date. At Uhrenkontor, the watch is checked at the handover, and an incorrect statement leads to an adjusted offer. You are also liable for warranted qualities under Article 197 of the Code of Obligations.
Does Uhrenkontor buy watches that need a service?
Yes. You can offer watches with a service due, without box and papers, or vintage pieces. Over 25 partner dealers in Switzerland assess the watch as it is, and the service is taken into account in the offer. State the last service in the form. Watches with a market value below around CHF 3,000 are not bought.
